Njengoba amabhizinisi amaningi ebona izinzuzo zokusebenza kahle kwamandla kanye nokusimama kwemvelo, kunesidingo esikhulayo samadivayisi anganciphisa ukusetshenziswa kwamandla kumishini yezimboni.Enye yezinto ezinjalo iyisiqalisi esithambile se-voltage ephakathi.
I-11kv motor ethambileabaqalayoaklanyelwe ukusiza ukulawula isiqalo semoto, esingaba phezulu kakhulu futhi sidle amandla.Ngokunciphisa ukuqala kwamanje, iziqalisi ezithambile zinciphisa ukucindezeleka emotweni futhi zandise impilo yayo, kuyilapho kunciphisa ukusetshenziswa kwamandla nezindleko.
Ngakho-ke, i-medium voltage motor motor soft starter isebenza kanjani?Konke kuqala ngokunikezwa kwamandla.Lapho isiqalisi esithambile sinikwa amandla, sisebenzisa uchungechunge lwemishini yesimo esiqinile, njenge-thyristors, ukukhulisa kancane kancane amandla ogesi alethwa enjinini.Yilokhu kuphakama kancane kancane okuqanjwe ngakho isiqalisi esithambile, njengoba kuvumela injini ukuthi iqale kahle futhi kancane.
Njengoba i-voltage ikhula kancane kancane, amandla okuqala e-motor anomkhawulo, okunciphisa ukuguga nokudabuka kuma-motor windings nezinye izingxenye.Lokhu kuvumela injini ukuthi isebenze kahle kakhulu futhi inokwethenjelwa, inciphisa amathuba okuhluleka kungazelelwe noma ukwehluleka.
Ngokungeziwe ekwehliseni ukuqalisa ukusetshenziswa kwamanje namandla, iziqalisi ezithambile ze-voltage emaphakathi zisiza ukuvikela kuma-voltage sags kanye noshintsho lukagesi wamapayipi olungalimaza injini noma ezinye izinto ezixhunyiwe.
Yebo, akuzona zonke iziqalo ezithambile ezidalwe zilingana, futhi kunezici eziningi okufanele uzicabangele lapho ukhetha isiqalisi esithambile esilungile sohlelo lwakho lokusebenza.Izinto ezifana nesilinganiso semoto, izici zomthwalo kanye nezidingo zamandla esistimu zidinga ukuhlolwa ngokucophelela ukuze kutholwe isiqalo esithambile esingcono kakhulu sezidingo zakho.
Ukucatshangelwa okubalulekile lapho ukhetha isiqalisi esithambile imvamisa yokushintsha.Imvamisa yokushintsha inquma ukuthi idivayisi yesimo esiqinile esetshenziswa kuziqalisi ezithambile ivulwa futhi ivalwe kaningi kangakanani.Imvamisa yokushintsha ephezulu ivumela ukulawula okunembe kakhudlwana kwamandla okuqala futhi kunciphisa ukucindezeleka emotweni, kodwa futhi kwandisa ukushisa okukhiqizwa yi-starter ethambile futhi kufinyeze ukuphila kwayo.
Ezinye izici okufanele zicatshangelwe lapho ukhetha isiqalisi esithambile zihlanganisa izinga lokuvikela elinikezwa idivayisi (njengokuvikela i-overcurrent kanye ne-overvoltage), uhlobo lwephrothokholi yokuxhumana esekelwayo (njenge-Modbus noma i-Ethernet), kanye nokuthi isiqalisi esithambile singahlanganiswa kalula yini. kokukhona kwakho ohlelweni lokulawula.
Ngesiqalisi esithambile se-voltage emaphakathi esifanele, ungathola izinzuzo eziningi ezihlanganisa ukusetshenziswa kwamandla okuncishisiwe, impilo ende yemoto, ukwethembeka okukhulisiwe nokulawula okukhulu inqubo yakho yezimboni.Kungakhathaliseki ukuthi ulungisa kabusha isistimu ekhona noma ufaka injini entsha, isiqalisi esithambile sekhwalithi ephezulu singakusiza uhlangabezane nezinhloso zakho zokonga amandla nokusimama kuyilapho uthuthukisa ukusebenza futhi wehlisa izindleko zokusebenza.
